조각을 사용하는 안드로이드 이미지 그리드 뷰

Question

AppCompatActivity의 조각에서 이미지 그리드를 만들기 위해 만든 세 가지 Java 클래스를 모두 붙여 넣고 있지만 아래에 붙여 넣은 오류가 나타납니다.

내 주요 활동 :

public class MainActivityFragment extends Fragment 
{ 
    public MainActivityFragment(){ 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{ 
    ViewGroup root = (ViewGroup) inflater.inflate(R.layout.fragment_main, null); 
    GridView gv1=(GridView)root.findViewById(R.id.grid); 
    gv1.setAdapter(new ImageAdapter(getActivity())); 
    return root; 
} 

}

imageadapter 클래스 :

public class ImageAdapter extends BaseAdapter 
{ 
private Context ctx; 

public ImageAdapter(Context c) 
{ 
    ctx=c; 
} 

@Override 
public int getCount() 
{ 
    return pics.length; 
} 

@Override 
public Object getItem(int position) 
{ 
    return null; 
} 

@Override 
public long getItemId(int position) 
{ 
    return 0; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) 
{ 
    ImageView iv; 
    if (convertView == null) 
    { 
     iv = new ImageView(ctx); 
     iv.setLayoutParams(new GridView.LayoutParams(350,350)); 
     iv.setScaleType(ImageView.ScaleType.FIT_XY); 
     iv.setPadding(4, 4, 4, 4); 
    } 
    else 
    { 
     iv = (ImageView)convertView; 
    } 
    iv.setImageResource(pics[position]); 
    return iv; 

} 

private Integer[] pics={ 
     R.drawable.a,R.drawable.b, 
     R.drawable.c,R.drawable.d, 
     R.drawable.e,R.drawable.f, 
     R.drawable.g,R.drawable.h 
}; 

}

있는 gridview와

public class MainActivity extends AppCompatActivity { 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    if (savedInstanceState == null) { 
     getSupportFragmentManager().beginTransaction() 
       .add(R.id.main_fragment, new MainActivityFragment()) 
       .commit(); 
    } 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    int id = item.getItemId(); 

    if (id == R.id.action_settings) { 
     return true; 
    } 

    if (id == R.id.action_sort) { 
     showPop(); 
     return true; 
    } 

    return super.onOptionsItemSelected(item); 
} 

public void showPop() 
{ 
    View menuItemView = findViewById(R.id.action_sort); 
    PopupMenu popup = new PopupMenu(MainActivity.this, menuItemView); 
    MenuInflater inflate = popup.getMenuInflater(); 
    inflate.inflate(R.menu.sort_popup, popup.getMenu()); 
    popup.show(); 
} 


}

Answer 1

그것은 예외 오류입니다. 당신의 코드를 시도/캐치 주변에

java.lang.RuntimeException가을 시도 할 수 없습니다 활동 ComponentInfo {com.example.android.mymovieapp/com.example.android.mymovieapp.MainActivity}을 (를) 시작 : 자바. lang.IllegalStateException :이 활동에는 이미 창 장식으로 제공되는 바 작업이 있습니다. Window.FEATURE_SUPPORT_ACTION_BAR을 요청하지 말고 의 테마에서 툴바를 대신 사용하려면 windowActionBar를 false로 설정하지 마십시오.
